Device for distributing power between cathodes of a multipolar electrode, in particular of an implant
First Claim
1. Device (ES) for distributing power between n cathodes (Ki) of at least one multipolar stimulating electrode (EM) further comprising at least one anode (A), n being equal to or greater than two, characterised in that it comprises a reconfigurable current mirror (MC) comprising n outputs (K′
- i) capable of being coupled respectively to said n cathodes (Ki) and configured to supply to said n outputs (K′
i) n complementary fractions (Iki) of a control current (Idac) having respective chosen values which are substantially constant in the presence of an amplitude variation of said control current (Idac) so as to allow substantially constant spatial locating of the stimulation.

Abstract
A device (ES) for distributing power between n cathodes (Ki) of at least one multipolar stimulating electrode (EM) comprises at least one anode (A), wherein n is equal to or greater than two. Said device (ES) comprises a reconfigurable current mirror (MC) which is provided with n outputs (K′i) connectable to said n cathodes (Ki), respectively and supplies to the n (K′i) outputs n complementary fractions of a control current having respective selected values which are substantially constant at the control current amplitude variation in order to carry out a substantially constant spatial location of stimulation.
